"The responsibility to issue drivers’ licenses and establish driving laws has always been given to individual states, and requirements vary among states. In 1903, Massachusetts and Missouri became the first states to have laws about licensing, and in 1908, Rhode Island became the first state to require a driving test. By the 1930s, many high schools began to offer formal driver education classes. In years prior, the responsibility for teaching new drivers had fallen on car salesmen, family, friends, or organizations such as the YMCA. Despite concern about the safety of drivers on the road, in 1935, just 37 states required drivers’ licenses and few required a test to earn such a license. Today, all 50 states have laws requiring drivers to pass a driving test in order to gain a license. However, there is still disagreement about whether 16-year-olds are too young to drive."
